Hello and thank you for looking at my post.

I have all of a sudden been exposed to my screen flickering. I open up a web browser and go to a site and SHORTLY after the screen starts flickering up and down. ( makes it a bit hard to read stuff)
Not so much the LCD screen flickering but the words inside the open screen, jump up and down. Other windows, the wording jumps from left to right. there doesn't seem to be any particular sequence to it all.
Can someone suggest a method to track this down please?

This machine has Win XP Pro SP3, 1.5 Gig RAM. Celeron CPU 2.8 GHz.

This jumping inside of open windows is not limited to just web browsers IE, F/Fox, Chrome or OPERA so on. It also occurs with Control Panel or Windows Explorer activities.

It makes editing, a real task when I try to rename a file.

I have a few other screens about, I'm going to change over to another one to check the monitor, but I expect that will not change anything.

I have a feeling that this is more internal (I could be wrong of course)

Perhaps a virus or a new program installed might be causing it. This computer only has a normal corded mouse and keyboard. There are no other peripherals added at this time.

Wouldn't you know it... it has settled down all the time I've been writing this. Hmmm?
I use Windows Essentials as my virus software currently, but essentials doesn't show any problems. ( Doesn't mean a great deal really)

Any suggestions greatly appreciated.
Thank you.

Remove and re-seat your vid card...
Also re-install the vid card drivers.Consider the monitor cable as a SUSPECT as well. Check for tightness of connections. Walk the cable hand over hand and look for damage or depression in the cable indicating that it was crushed by door, feet, chair, or setting the table on it if the table was moved. If you have the opportunity try borrowing a cable from a friend to see if it fixes it. Just be sure to return it when testing done.Thank you patio and Sn3akyP3t3 for your reply.

Patio, that reminded me that I have had some trouble in the past with this computer. I ended up loading an Intel Extreme Graphics 2 (driver or something) for it.
So what Im going to do is start from the box, external and replace the screen, cable and power supply. Test that and see if there is a change. If there's no change then I'll get to the inside bits.

Sounds LIKE Sn3akyP3t3 lent some stuff and didnt get it back. I dont have that problem with friends not giving stuff back... I dont have any friends.. Hahahaha ... anyway I dont need to borrow any of that sort of stuff, I have a box here somewhere with enough of anything to swap over bits. But a good suggestion thanks.

I just thought that this has only started since I got a new voip modem..
I dont suppose that might have any influence in display.Actually, I'm a clepto. All your base are belong to us. Hi, just an update on this. I changed screens to another lcd and so far the wiggles have stopped.
Im guessing it was the screen malfunctioning.
Maybe a power supply problem causing the fluctuations.

I am going to put the old screen onto another computer to test that theory.

And Sn3akyP3t3, can I have my stuff back...... Pleaaaaseeee!!!
